目的：目的探讨动脉自旋标记（ASL）灌注成像在乳腺癌诊断中的可行性。材料与方法：13例女性原发性乳腺癌患者纳入本研究。所有检查均在1.5特斯拉MRI系统上进行。对彩色灌注图和MRI灌注值的视觉评价进行了评估。结果：14个肿瘤病灶中有13个在彩色灌注图上显示。8例乳腺进行了CT灌注检查，CT灌注和MR灌注的血流值之间的关系显示出显着correlation.Conclusion：非增强MRI成像的ASL技术是有效的，乳腺癌的MR灌注值被认为是有助于定量诊断乳腺癌。
Purpose: To investigate the feasibility of perfusion imaging using an arterial spin labeling (ASL) technique for breast cancer.Materials and Methods: Thirteen female patients with primary breast cancers were included in this study. All examinations were performed on 1.5 Tesla MRI systems. Visual evaluations of the colored perfusion map and MRI perfusion values were assessed. MRI and computed tomography (CT) perfusion values were compared.Results: Thirteen of 14 tumor lesions could be visualized on the colored perfusion map. CT perfusion examinations were performed in eight breasts, and the relationship between the blood flow values of CT perfusion and of MR perfusion showed a significant correlation.Conclusion: Nonenhanced MR imaging by an ASL technique is valid for depicting breast cancer, and the MR perfusion value is thought to be helpful for quantitative diagnosis of breast cancer.
